ROTARY BEATER.

Specification of Letters Patent.

Patented May 9, 1916.

. Application filed September 2 1914. Serial No. 863,540.

To all whom it may concern:

Be it known thatwe, GEORGE L. CAMPEN and DEAN NoYEs, both citizens of the United States, and residents of Omaha, 1n the 5 countyof Douglas and State of Nebraska,

have invented certainnew and useful Improvements in RotaryBeaters, of which the following is a specification.

Our invention relates to crushing and pulverizing machines, and more partlcularly to machines of the class characterized-by r0- tary heaters or hammers revolving withln a cylindrical cage. I

It is'the object of our invention to provide in a machine of this class means adapting the same for breaking, "pulverizing and disintegrating all kinds of materials, including adhesive, gummy, gelatinous and fibrous materials, and mixtures thereof, such as ordinarily might clog the interstices of the cage and prevent or retard the escape of other materials from the crushing chamber. (I

In the accompanyingdrawings, Figure 1 is a partial side view and partial vertical sectional view of a machine embodying our invention, Fig. 2 is a transverse vertical sec-' tion of the same, and Fig. 3 is an end view of the main casing or housing, showing the driving mechanism for the revolving cagebars. The sectional portion of Fig. l is taken on the plane of the line a2a: of Fig. 3. In the structure illustrated, we provide a horizontal main shaft 1 which is journaled in suitable bearings 2, the same being mounted on foundation-blocks?) as shown in Fig. 1. On the ends of the shaft are secured pulleys 4 which may be connected by belt with a suitable source of power, for revolving the shaft at a high speed. Adjoining ,the inner ends of'the bearings, fly-wheels 5 are secured to the shafts. The central portion of the shaft is square in section, and on said portion thereof there are mounted a plurality of beaters or striking-devices, each site sides of the shaft, as shown in Fig. 1.

Inclosing the central portion of the shaft" comprising a hammer or head-block 6, a"

l is ahousing or casing which, in the structure shown, is formed by end-plates 10 and 11, side-plates 12 and 13,'a top-plate l4 and a bottom-plate 15, the said plates being reinforced and connected to each other by angleiron corner-pieces 16, arranged as shown, and riveted to the plates. The casing is separable on a horizontal plane passing through the axis of the shaft, and the upper and lower portions are; detachably secured to each other by bolts 17 which extend between the angle-iron edge-pieces '18 at the sides of the casing. At one side of the upper portion of the casing is a feed-chute 19: Within the lower portion of the casing, at the sides and near the bottom thereof are deflecting-plates 20 which form 'a chute for directing materials through a. discharge opening in'the bottom-plate 15.

On the inner sides of the end-plates 10 and 11 are secured the cage-rings 21, the same being disposed concentrically with the main-shaft 1. The upper part of the cage isformed by square bars 22 which extend longitudinally between the cage-rings, be ing parallel with each other and with the "shaft 1, and their. ends fitting into suitable openings in the rings. The lower part of the cage is formed by cylindrical rods or shafts 23 of which the end-portions extend throughethe cage-rings and are, revoluble in bearingsformed in bearing-blocks 24 secured on the outer sides of the end-plates 11. At one end each of the shafts 23 has a small gear 25 secured thereon, the gears being so proportioned that they will mesh serially to form a continuous train. Qne .of the shafts has a longer end-portion than the others and-on said shaft'is secured a bevel gear 26 which meshes with a bevel pinion 27 carried on the lower end of a shaft 28. Said shaft is journaled in a bear-* ing 29 secured on the end-plate 11, and at its upper end carries a worm-wheel 30. The worm-wheel meshes with a worm 31 which is secured on the main-shaft adjacent to the end of the casing. By means of the worm,

worm-wheel, bevel-gears, and train of gears 25, rotation of the shaft ,1 causes the shafts 23 to revolveat relatively directions indicated.

Adjacent to each of the shafts or revoluble cage-bars 23 there is a scraper-bar 32 which extends through slots in the ends of the casing, and of which the edge is pressed yieldingly against the respective shaft by low speed in the means of springs 33 which are disposed L beneath the projecting ends of the scraperbar. outside the casing. Adjust1ng-screws 34 are provided in brackets 35, for varying the compression of the springs. The operation of the mechanism Will b apparent. vThedirection of rotation of/the shaft 1 is as indicated in Fig. 2, or sothat the heaters move downwardlv on the side adjoining the feed-chute 19. Materials introduced into the cage through the feedchute are struck by the heaters and thrown against the cage-bars, being thereby broken and crushed so as to be able r29 pass between the bars and fall through the dischargeopening in the bottom of the casing, or be directed thereto by the plates 20. Any material adhering to the revolving cage-bars is carried to {the outside of the cage and then dislodge; from said bars by the scraper-bars 3 The described machine has been found particularly effective for breaking up and self-cleaning.

lodge'almost altogether on the bars at the lower part of the cage, and especially on 40 those immediately adjoining the lower end of the feed-chute. For this reason, with all materials that have been experimented with, it has been found unnecessary to provide revolving cage-bars except at the lower part of the cage and on the side adjoining the feed- .chute,'but it'will be apparent that, if desired, the entire cage might be made up of revoluble bars.

Now, having described our invention,

what we claimand desire to secure by Letters Patent is:- I i y 1. In a rotary crushing machine, a revoluble beater-shaft, a cage comprising a series of bars arranged in cylindrical form about the axis of said shaft, some of said bars being revoluble about fixed axes, and actuating means connecting said beater-shaft and said revoluble bars.

2. In arotary crushing machine, a revoluble beater-shaft, a cage inclosing thesame and having bars revoluble on fixed axes, and actuating connecting means between said beater-shaft and said revoluble cage-bars 3. In a crushing machine, a revoluble beater-shaft, a cage disposed around the same and comprising a series of parallel spaced rectilinear bars, some of. said bars being revoluble on fixed axes, actuating connecting means between said beater-shaft and said revoluble bars, and scraper-bars engaging said revoluble cage-bars externally of the cage for dislodging materials therefrom.

4. In a crushing machine, a revoluble beater-shaft, a cage disposed around the same and comprising a series of spaced bars extending parallel with the beater-shaft, a chute for directing materials into the cage at one side'thereof, some of the bars adjacent to said chute being revoluble to carry materials from the inside to the outside of the cage, scraper-bars engaging said revo- Iuble cage-bars on the outer sides thereof, and means for pressing said scraper-bars yieldingly toward the cage-bars;

In testimony whereof we have hereunto subscribed our names in the presence of two witnesses.
